Some of the most common powder handling problems arise when conveying from storage silos or bins into production.

Often
the powder or grain will have been motionless for hours, days, or even
weeks before flow is required. Over this time, most powders or granules
will compact with the result that far more energy is needed to cause
flow than in aerated samples. On the other hand, powders used
immediately after transport, which may have involved agitation or more
pronounced vibration, will have been aerated and flow more easily than
others that have been stored.
